====== Automatic reload node.js files ======

We'll use nodemon for this.
<note warning>
Nodemon is a tool meant for development. It should not be used in a production environment.
</note>

===== Install =====

To automatic load the files, without a restart being needed, we should install:
<code>
npm install --save-dev nodemon
</code>

The --save-dev flag saves nodemon as a development dependency, meaning it won't be installed in production environments. \\ \\ 

===== Usage =====

==== Use nodemon instead of node ====

Once installed, you can start your application with nodemon instead of node. For example, if you have a file server.js, you would start it with nodemon as follows:
<code>
npx nodemon server.js
</code>

This starts the server.js application and monitors for any changes. \\ If nodemon detects any changes in your source files, it will automatically restart your server.

==== Npm scripts ====

You can also add nodemon as a start script in your package.json. This way, you can start your application with nodemon by running npm start. \\ 
Here is an example of how you would do this:
<code>
"scripts": {
    "start": "nodemon server.js"
}
</code>

To run it:

<code>
npm start
</code>
